Analysis
The Good & The Bad
What We Like
- Sapphire crystal — exceptional at this price
- Seiko NH35/NH36 — reliable, widely serviceable Japanese automatic
- 40mm case — versatile wrist presence
What Could Be Better
- 62m WR — safe for swimming but not diving; avoid hot showers (gaskets degrade)
- NH35/36 accuracy is -20/+40 sec/day — you'll adjust time weekly, not COSC-grade
